UV222 Downlight


Designed for effective overhead Far-UVC decontamination, the UV222 Downlight ensures clean air and surfaces in various settings. It fits seamlessly into different environments without affecting the people present.

Supplier:

UV222 Downlight

The UV222 Downlight is an overhead, ceiling-mounted Far-UVC disinfection solution engineered for continuous decontamination of air and surfaces in occupied spaces. Featuring programmable modes and dual beam-angle options, it delivers safe, non-chemical pathogen control without disrupting operational flow.


Targeted Far-UVC Protection

Pioneering safe Far-UVC disinfection at 222 nm, the UV222 Downlight exploits pathogen absorbance characteristics to neutralise viruses and bacteria while remaining harmless to human skin and eyes—enabling continuous operation in spaces where people are present.

Programmable Performance & Configurability

Available in two beam-angle variants (60° and 100°), each unit is individually measured and shipped with its unique output profile, delivering controlled, consistent irradiance. Programmable modes—including continuous use, duty-cycle, and motion-activated options—enable both energy efficiency and adaptive response to occupancy.

Technical Excellence & Long-term Reliability

Powered by a krypton-chloride excimer lamp, the UV222 Downlight delivers up to 115 mW (60°) or 70 mW (100°) in the Far-UVC range, while consuming just ~20 W. Each lamp ensures an exceptional operational lifetime of over 17,500 hours, with no ozone emission — offering sustained microbial control with minimal maintenance.

Seamless Integration & Installation Versatility

Designed for quick insertion into standard suspended ceilings via a 150–155 mm circular cut-out, the UV222 Downlight installs flush with a clean, unobtrusive profile. This enables easy retrofitting into existing infrastructure across a variety of clinical, educational, and public-facing environments.

Proven Applications Across High-Risk Settings

With established deployments in ICU rooms, schools, offices, and corridors, the product demonstrates effective airborne and surface decontamination, even in high-traffic zones — widely recognised as one of the most promising methods to counter pathogen transmission post-pandemic.

Compliance & Safety Assurance

Engineered in full compliance with regulatory standards governing 222 nm UVC exposure, each UV222 Downlight adheres to stringent guidelines for photobiological safety and human exposure thresholds — reinforcing trust and reliability in medically critical installations.

Long-Term Reliability
Built with a solid-state electrolytic dehumidifier, the system mitigates internal corrosion. The primary seal is inspectable, replaceable, and recommended for renewal every five years to sustain compliance in sterile environments.

Flush-Mounted Aesthetic
Designed for seamless integration into ceiling tiles, maintaining airflow dynamics and visual uniformity in cleanroom architecture.

Robust IP65 Protection
Rated IP65—fully dust-tight and protected from strong water jets—this unit can withstand routine sterilisation, high-pressure cleaning, and environmental exposure in demanding facilities.

Applications
Ideal for:
  • Pharmaceutical & biotech sterile manufacturing
  • Semiconductor & precision cleanrooms
  • Infection-controlled healthcare environments
  • High-level laboratory clean zones

Maintenance-Friendly Engineering
A rear-access module with detachable screws allows quick inspections and lamp servicing—minimizing downtime and maintaining cleanroom integrity.
